My improved machine islmilt after the same general plan as the machine shown and described in Letters Patent ot' the 'United States No.A 261.907, granted to me August 1, 1882, and is for the same object, viz: the manufacture from the coil of wire ot' a complete bottling-wire by successive operations and without the intervention ol" hand-labor. The operations performed by this machine are the same-viz., the cutting, looping, twisting, and 6o depositing of the wire-as in the machine shown and described in the said above-inentioned Letters Patent; but substantial changes have been made in the mechanism iorperforniing the various operations, as also for controlling the movement of the wire from the reel, so that I am enabled by slight adjustment and without using more than one machine to produce bottling-wires of any desiredlength, of a greater or less twist, ot' any desired size ot' 7o loop, and deposit them in quantities of one hundred, five hundred, one hundred and fortyfour, or any other given number to suit the demands or the convenience ofthe user.

As an aid to a more complete understanding of certain details of the machine previously fully described, reference may bel had to the said Letters Patent, No. 261,907.

I will describe the various parts of the machine in the order of its operation in making 8o a bottling-wire. beginning with the reel for holding the wire, and using letters of reference to the accompanying drawings. The reel A, which holds the wire, is set on a spindle in a convenient position tothe feeding-rollers. The mechanism shown in Fig. 3 is provided to insure the proper rotation of the reel and consequent giving ofi of the wire as it is fed forward by the feed-rolls. This leaves the wire free to be fed forward, and prevents any tend- 9o ency ofthe wire to slip between the rolls. The

'mechanism consists of a ratchet-wheel, B, set

suitable material being interposed between the 9 5 Y reel and :ratchet to increase the friction. A

short lever, a, pivoted at one end to the spindle-support and at the other to the connecting-rod b, carries a feed-pawl, c, so pivoted to it that the taking end ot' the pawl is in contact with the ratchet-teeth and is held against them by the pressure of spring d. The connecting-rod b is pivoted to an upright lever, x', the lever being lpivoted at its lower end,

. fr, on the slide S of the bed-plate, and prorIS vided near its middle with a cam-truck, which moves in the cam-path f on the face of camwheel g, set on shaft E, the cam-path being of the form shown in Fig. 18. It will be plain that at every revolution of the cam-wheel the cam-lever is moved toward the ratchet-wheel, carrying with it the rod b, and pushing the feed-pawl cagainst the ratchet-teeth, thus turning the ratchet-wheel, together with the reel which rests on it, and causing the reel to give ofi the wire as the feed-rolls feed it into the machine. As the cam-wheel g completes its revolution the rods a and b are moved in the opposite direction, and the feed-pawl slips back over the ratchet-teeth, ready for the next forward movement. The reel A may ot' course be made fast to the ratchet-wheel, if required, in any case.

L is ailever, pivoted near the middle to the reel-support j, and arranged so that its free end may press against the under side of the reel A and stop its momentum when the feedrolls cease acting. and thus prevent any undue turning ofthe reel. Itis pressed against a smooth ring on the under side of the reel, and freed from contact therewith alternately by the revolution of cam-wheel g, the inner end of the lever being provided with a cam-truck, which moves in the cam-path 7c, cut, as shown, on vthe face of cam-wheel g, Fig. 20, and as theinner end is depressed by the cam the outer end will be raised and made to press against the smooth ring or path on 'the underside of the reel and stop its movement-,while when the inner end is raised by the cam the outer end will be freed from contact with the reel, and the reel will be free to be moved by the forward movement of the feed-pawl c, moving the ratchet-wheel on which the reel rests. The outer end of lever L,which touches the reel, is provided with an adj listing-screw, L', having a rubber cap for the purpose of producing greater friction when it touches the reel. Between the reel and the feed-rolls I find it best to set a series of small rolls grooved on their peripheries to receive the wire. These rolls are set, as shown, (see ed to me. Motion is communicated to them, however, by different mechanism, which consists of a gear-wheel, M, which meshes with the cogged hub B of the lower feed-roll, B. The gear-wheel M is driven by a slotted crank, N, set on the end of shat'tl. At the outer end of the crank a connecting-rod, O, is pivotedto a slide which moves in the slot m, the slide being arranged so that it may be set at any point -in the slot, and thus get alonger or lshorter action of the crank, as will be apparcnt. The other end of the connecting-rod O is pivotcd to a lever, P, one end of which is set on the end of the stud p, on which the wheel M is also set, while the other end of lever P carries the propelling-pawl g and mechanism for setting the pawl against and freeing it from the gear-teeth on the wheel M. The end ot' the rod O is pivoted to the clutch-operating lever R near its middle and to the lever P, the pivot-hole in the lever P being slightly elongated, as shown, Fig. 9, s o as toA allow a slight play of the pivot in the hole in order to actuate the clutch-operating lever R suffi` ciently to force the propelling-pawl q int-o contact with or free it from the gear-wheel M. The lever R,which operates the clutch, is ot' the shape shown, and is pivotcd at R to the upper part of the lever P, and near the middle to the connecting-rod O, u hile at its bearing end it carries a beak, r, which operates in a V-shaped notch, t, in the pawl to tilt the pawl and cause it to take with or be free from the gear-teeth on the wheel M. The pawl q, as will be seen, is pivoted to thelower end of lever'P.

The operation of this mechanism for driving the wheel M and the feed-rolls is as follows: The lever P and pawl q, before beginning to act on wheel M, appear at the right of the Wheel as viewed from the front ot' the machine, Fig. l, (see also Fig. 7,) and the crank N is on the right of its shaft. The pawl g, it will be obvious, will be free from contact with wheel M, since the lever R will he pressed back by reason of the pivot-pin in the end of rod O moving to that side of its slot in lever P, thus causing the beak of lever R to bear against the side of the V-shaped notch in pawl q, and raising the benk of the pawl from contact with the gear-teeth. If, now, the crank continues its revolution, it will move downward and toward the left of its shaft, carrying with it the connecting-rod O, the pivotpin of which will slip to the opposite side of the slot in lever P, carrying with it lever R, the beak of which will now press against the other side ofthe V-sliaped notch in the pawl, thus forcing the beak ofthe pawl into contact with the gear-teeth on wheel M. As the revolution of the crank continues the wheel M is turned until the crank begins to move toward the right again, when the rod O is pressed back, pressing the pawl q, and carryingthe pawl mechanism back to repeat the forward movement again as the crank again passes IIC IZO

the horizontal and begins its movement to the left. By actuating the feed-pawl g in this manner I obtain a movement of wheel M, which begins slowly, increases in rapidity to the middle of the movement, and ends slowly, which is desirable in this class of machines. I also am enabled to move the pawl back after each forward movement free from contact with the gear-teeth, instead of dragging it back on them, thus preventing wear of the pawl and teeth, and rendering the mechanism noiseless. The wire passes from the feedrolls through the cutters, one of which is stationary, k1, and the other movable, k, made and actuated in the manner shown in the said Letters Patent, No. 261,907, granted to me. I prefer, however, to set the cutting-holes in the cutters through which the wire passes and by which it is cut, in pieces of steel, (shown at t, Fig. 2,) so that when the cutting-edges of the holes require sharpening the pieces may be removed and sharp ones inserted in their places. The conductor G, which conducts the wire from the feedrolls and cutters to the twistingclamps, is also the same in position and inode ot' operation as in the former machine, shown in the aforementioned Letters Patent. It is hinged, however, on the opposite side, nd is provided with au extension, G, which may be attached to it by screws c c when a long bottling-wire is being made. The lid of the conductor G is opened by downward action of cutter-lever s on arm s4, projecting from the lid. The lever s" operates the movable cutter it by means of connecting-rod s, camlever s, and cam sl in camfwhecl S8 on shaft Il, as will be readily understood.

In order to make bottling-wires of any length on the same machine without loss ot' wire or subsequent manual op eration, I found it necA essary to be able to vary the distance between the cutters and the clamps which seize and twist the wire, this distance being that which determines the length of the wires. To do this, I place the parts of the machine which have thus far been referred to, which include the reel and reel-operating mechanism, the feeding and cutting mechanism, and the conductor, on a slide, S, in the bed-plate. (See Figs. l2 and 13.) This slide is ofthe dovetail form in cross-section shown in Fig. l2, and fits in a corresponding` groove or recess in the bed-plate. Y @ne side of the recess is iitted with an adjustable side ,or strip, el, against which the adj Listing-screws to bear, which enables it to be set with relation to the slide, as will be readily understood. The set-screw y is fast in a stud'piece, e', secured by screwbolts to the end ot' the bed'plate, and works in a hole in the slide fitted to receive the screw. By putting a crank on the square head ofthe set-screw the screw may be turned and the slide moved outward or inward, thus increasing or diminishing the distance between the cutters and the seizing and twisting clamps, and thus enabling the machine to make a longer or shorter bottling-wire, as may be required. The secondary shaft E, which actuates the parts on the slide in the bed-plate, is journaled into two uprights, F and F, which rise from the slide. The upright F also supports one end of the main shaft E, which is set at right angles to the secondary shaft, and is connected with it by the ruiter-gears H H. The upright F is free to slide back and forth under the shaft as the slide in the bed-plate on which it rests is moved, and the gears retain their same relative position, the gear I-I being keyed to the main shaft by grooving the shaft lengthwise and using a feather or key in the well-known manner, which allows the gear to be slipped in a direction lengthwise ot' the shaft. When the slide of the bed-plate is set back,and the machine arranged to make short lengths of bottlingwires, the end of the main shaft E will project to the right of the upright F, when the machine is viewed as shown in Fi 2, The mechanism which seizes and twists the wire is operated directly by the main shalt FJ, and rests not on the slide but on the stationary part of the bed-plate. This mechanism is supported on a stationary frame, J, of the same general shape as the reciprocating frame shown in the aforementioned Letters Patent granted to ine-that is, it is of an inverted Y or yoke shape, as shown. (Figs.l

l and 2.) rihis frame .I is secured to the bedplate, and supports the main shaft E', which is journalcd to it, and which carries inside the yoke-shaped frame the cam-wheels T and U, which operate the seizing, twisting, and bending mechanism. rEhe twisting-clamps a are mounted in a box, c2, on the end of the hollow spindle a3, journaled inthe frame, as shown, and through which the rod b2 projects to operaie the toggles which open and close the clamps. The outer end of the rod b2 is heldin contact with the cam-lever c by checknuts c c. The inner check-nut, ci, is provided with a hub projecting toward and against the outer nut, et. rIhe end ofthe cam-lever c is Y- shaped, the Y embracing the hub on the checknut c". The cam-lever o' is pivoted near its middle to a projection of the frame, and carries at its lower end a truck which acts in the cam-path M. 'lheinward or outward move ment of the rod Z)2 opens or closes the toggled clamps a', as will be readily understood.

In order to twist the wire, the spindle a3 is revolved, carrying with it the clamps a. To effect this, the spindle is provided with the bevel-pinions d d2, keyed to it in the wellknown manner, so that the pinion may be slipped along the spindle and thus brought in contact with or freed from its gear, as desired. The gears d,3 d" are in one wheel, made as shown, Fig. 4, which is set on the upper end of the upright shaftf, which is journaled in the frame J. The lower end of the shaft is fitted with a pinion, f3, which meshes with the gearvsegment j", fast to the periphery of cam-wheel U. The pawl ku, pivoted to the IOO frame, is actuated by a spring, 7am, which acts to throw it against the pinion f3, and by the rider f* fast to the cam-wheel, which acts to free it from the pinion while the pinion is in contact with the gear-segment. This rider is so arranged that as the segment passes the pinion the rider will have passed the pawl, thus allowing the pawl to be thrown against the pinion and hold it iirmly in position. By

this means any uncertain movement of the pinion, and consequently of thc twistingclamps, is avoided. The double gears d3 d4 at the upper end of the upright shat'tf and the two bevel-pinions d d2 are provided to enable the same machine to produce wires of greater or less twist, as desired. Vhen less twist is desired, the pinion d is slipped into position to mesh'with the gear. cl3, and the pinion d2 is slipped back andout of contact with gear d4. Twice the number of twists can be obtained by reversing` the position and allowing the spindle a to be revolved by pinion d2 in contact with gear d, as will be readily understood. A support, F2, rises from the bed-plate, and stretching between this support and the frame J are placed a guide-rod, g, and a rock-shaft, h. The guide-rod supports the head 7c', which reciprocates upon the rod, and which forms a support for the gri ppers k2. The grippers are pivoted to the front ofthe head and are opened and closed by a toggle-connection with .the piece p', which slides on the lower guide-rod, g2. .Thisrod g2 is connected with the rock-shaft h by the pieces h2, and is raised \or lowered to open'or shut the grippers k2 by means ofthe connecting-rod q and cani-lever g2, the connecting-rod being pivoted at its upper end to the-lower guide-rod, g2, and at its lower end to the cam-lever q2, as shown at g3, Fig. l. The cam-lever is pivoted at g4 inside the frame J, and is provided with a camtruck which acts in the cam-path g5 in camwheel T. This cam-path is shown in Fig. 23.

It will be obvious that at each revolution ofthe cam-wheel the grippers k2 will be opened and closed, and that by means of the lower guide-rod, g2, set on its rock-shaft lz the camlever may act to open or close the grippers k2 irrespective of their position on the guide-rod g-that is, whether the head lc', supporting the grippers, be slid forward on the guide-rod g toward the support F2 or back toward the frame J.

The grippers 7c2 perform three functions. They guide the wire from the end of the conductor between the open twisting jaws or clamps a. They also move forward toward support F2 when the clamps a have closed, thus sweeping the ends of the wire together and bending the wire around thejaws ofthe clamps forming the loop; and, further, as the ends are thus brought together, they close on the wire and hold one part of it stationary, while the twisting-'clamps a are acting to twist the portion between them and the grippers k2.

In order that the grippers lc2 may form guides.

for the wire as it leaves the conductor, the pieces p2 are provided, pivoted centrally to the side of the head 7d, and formed as shown, Figs. 27, 30, and 3l, so that when4 the grippers 7c2 are open and drawn back toward the frame J, so that the clamps c lie between them, the forward ends ot' the pieces p2 are in contact with the under side of the gripperjaws and form with them iiaring eyes, which receive and guide the wire between the clamps a. The forward ends of the pieces p2 are pressed up against the under side of the gripper-jaws by reason of the rear end of the pieces coming in contact with the pins p3, set in frame J, whenever the head slides back to the frame. Vhen the head moves forward, the rear ends of piecespZ move from under the pins p3, and the spiral springs s, fast at their Alower ends to the head It', act to pull down the forward ends of the pieces p2 away from the grippers, thus allowing the ends ofthe wire as they sweep round by the forward movement ofthe head and grippers to come together. When the ends ofthe wire are'brought together, the toggle mechanism acts, and the grippers close and hold the wire stationary while the twisting-clamps a are acting. One jaw ofthe grippers is faced with a strip of steel, 310, adj usted .by screw su. This allows the jaw to accommodate itself to wire oi' different sizes with out special adjustment. The opposite jaw is fitted, where it comes in contact with the wire, with a piece of hardened steel, which, when worn, may be easily and speedily replaced. The reciprocating motion of the head k 1s obtained by means of the connecting-rods and adjustable slotted cam-levers t t2, and cam t3 in the face of cam-wheel U. (See Fig. 4.)' The cam-lever t, which carries the cam-truck, is pivoted to the inside of the frame J, and is slotted at its upper end, so that it may be secured at any point in the slot by the sliding pivot t4 to the slotted lever tf, which is pivoted at its lower end to frame J, and at its upper end to the connecting-rod s.

It will be obvious that to obtain a greater or less throw of the lever, and consequently a greater or less length of slide to the head k', and so allow a greater or less portion of the wire to be twisted, it is only necessary to secure the sliding pivot t4 at a higher or lower point in the slotted levers t t2, and to obtain a throw of extra length the pivot t5 may be changed and set in the hole t6, thus increasing the length of the lever above the pivot, and consequently largely increasing the length of its throw.

The counting mechanism (see Fig. 6) consists of a ratchet-wheel, w', set on a spindle, to2, projecting from frame J, the feed-pawl o2, retaining-pawl c7, actuating-lever v3, and cam e, provided with cam-path 815, the pinion 1 also set on spindle 102, and gear i 2, set on spindle ya, on which is also set the rider-wheel y, on the periphery of which the lower pawl, w3, rides'.` The ratchet is provided with a. hub,

ICO

IIO

ISQ

projecting outward along the spindle w?, and fitted with grooves into which corresponding iianges on the hub ofthe pinion y fit, to insure the revolution ofthe pinion with the ratchet.

0n the hub of the ratchet is journaled the elbow cam-leyero, bearing at one extremity the feed-pawl et, and at the other a cam-truck which runs in the cam-path S15. The retaining-pawl nl is pivoted, as shown, Fig. 6, on the side ofthe frame. and prevents any backward movement of t he ratchet w. It will be obvious that at each revolution ofthe canrwheel the i'eed-pawl will feed the ratchet forward one tooth, and that as the ratchet and pinion are keyed together the pinion performs a complete revolution whenever the ratchet does. The gear @jl is keyed or looked to the projecting h uh of the plain or rider wheel y" in the same 'manner as the pinion and ratchet just described are locked together, and the two therefore re volve together on spindle 1/3. The plain or rider wheel if is provided with a notch, p", on its periphery, into which the end of the pawl w is forced as the notch comes over it, the pawl being set fast on the rock-shaft p5, actuated in the well-known manner by spiral spring sa, (see Fig. 1,) fast at one end to the shaft and at the other to the foot of frame J. If, now, the pawl drops into the notch, the rock-shaft is turned by the spiral spring sufficiently to throw the end of the shipper-lever P in contact with the clutch mechanism, and he drivingpulley P2 is unlocked from the shaft and made a loose pulley, and the machine is stopped.

Any form of clutch mechanism may be used; but I prefer to use t-he form shown in the drawings, and which is more fully shown and described in an application for Letters Patent filed by me the 23d day of September, A. D. 1882. It will be plain, therefore, that as a complete bottling-wire is made ateach revolution of the main shaft, if the gear y? be provided with five times as many teeth as thepinion y', and the ratchet-wheel be provided with one hundred teeth, the gear will complete a revolution to each five hundred revolutions of the main shaft, and that at each revolution of the gear the plain or rider wheel will complete a revolution and its notch p" will come under the pawl to3 and stop the machine7 thus stopping the machine whenever tive h undred wires have been made. It will be obvious, also, that several sets of gears and pinions may be made with each machine, the teeth of Which may be proportioned to cach other, so as to produce a complete revolution of the gear, and consequently of the iiderwheel, when a greater or less number of revolutions of the shaft have been made, and by substituting these on the machine for the gear yt and pinion i/ the machine may be stopped when any given nurnber of wires have been made.

The operation of the machine is as follows: The reel is started by the movement of the ratchet on which it rests simultaneously with the movement of the feeding mechanismto feed forward the wire, so `that the work ot' moving the reel is not done by the feed-rolls. W'hen the reel is revolved by the feedArolls in 7o drawing the wire from it, the wire is apt to bind on it and will not give off' freely, unless the reel be specially filled from the coils of wire, which necessitates labor and expense. By this mechanism, however', I am enabled 75 to use the wire from the coils and without reeling it. rlhe wire passes through guide x10, under the eccentric prcssurcpin fr, between the feed-rolls, and through the cutting-holes into the conductor. The pressure-pin x12 is 8o set tightly in the frame, but so that it may be turned and set in any position, the friction of the pin in its hole holding it securely. rllhe pin is sufficiently long to project over the wire, and is provided at its outer end with an ec- 85 centric head, so that by turning the pin a greater or less degree of pressure of the head against the wire may be obtained. It is found in working some kinds of wire that the Wire has a tendency to curl slightly after leaving 9o the conductor, and thus is liable to miss the eye c of the grippers. A slight pressure obtained by the eccentric head ot' the pin x12 p revents this tendency to curl, and causes the wire to pass straight through the eyes of the grippers. From the conductor it passes through the eyes as, formed by the grippers 7a2 and pieces p2, passing between the open jaws of the twistingclamps af, and is run through so that it projects as far on the other side of the twisting-clamps c as the distance from the clamps to the cutters. This is to make a bottling-wire having legs of equal length. lf one leg is to be shorter than the other, then it will be plain that the feed-rolls must be set to feed a less length of wire forward. When the wire has been fed forward sufficiently, the reel and feed mechanism stop, the clamps c' close, and the cutterl tilts to cut the wire and open the lid of conductor G. The head and gripper-s now slide forward, bending the wire around the jaw-pieces am of clamps c. (The size of the loop depends up- IXO von the size of these jaw-pieces, several pairs of which are furnished, which may be used for different sizes, as desired.) lfvlhen the head has slid forward a sufficient distance in front of the jaws, the grippers close and hold the wire stationary, the clamps now revolve with spindle c3 and twist the wire, then open, and the wire drops out. A slide or receiver may be placed, as indicated, Fig. 4, underneath the clamps, to receive the wire as it leaves them and carry it clear ofthe machine.

ln driving the machine at a high rate of speed I find it convenient to use the att-achment shown at the right of Fig. 4 for tilting the slide I, on which the completed. wires drop in order to free them instantly from the twisting-jaws, and thus keep the machine clear. It' the slide I be kept stationary, the completcd wire may not leave the twisting-clamps -bow I is tilted, thus tilting the slide and dis- -mon construction, (which enables it to be cara rapidly `enough to be clear before the succeeding wire is seized. In order to insure this, I provide the attachment shown at the right of Fig. 4t to tilt the slide. It consists of an elbow-lever, I, pivoted at the elbow to the upright F2, and Ahaving the slide I secured to its upper end. The arm I2, soldered on the under side of the slide, iitsin a hole in the top of the lever and is secured there by a setscrew. The other end of the lever is pivoted to a connecting-rod, I3, the upper end of the rod being set on the lower guide-rod, g2. As the guide-rod is raised and lowered in closing l and opening the toggled grippers k2, the elcharging the wire which has fallen upon it by the same movement that closes the grippers k on the succeeding wire and keeping the machine clear.

I also 13nd it convenient in using some kinds of wire to give the reel a continuous movement, so that it will give oft' the wire ready for the feed-rolls by a continuous rather than an intermittent motion. This may be easily effected by removing the :reel actuating and stopping mechanism shown in the drawings and previously described, and substituting therefor an extension-shaft secured directly to the end of the main shaft E. This extension is provided with a universal joint of comried at an angle over to the reelspindle,) and at its end carries a bevel-gear, which meshes with another bevel-gear set on the reel-spindle in place of the ratchet-wheel shown in the drawings. This extension-shaft may be supported by a stud rising from the bed-plate or projecting from the arm j, which supports the reel. The reelin this'case will then rest upon the bevel-gear instead of upon the ratchet, and will revolve as the gear vrevolves with the revolution of the main shaft.
